Application filed August 4, 1914.

This invention relates to new and useful. improvements in brake shoemechanlsln.

The primary object of the invention is to provide brake shoes suspendedin an advance of the car wheels and adapted for lowering into brakingposition upon the track rails when released for such movements.

A further object is to provide brake shoes at each end of a car operableby levers extending to operative positions upon the car, and in whichthe brake shoes are adapted to be brought beneath and removed from theadjacent car wheels.

A still further object is to provide swinging arms upon a car operableby ahand lever and having suspended thereon a pair of brake shoesadapted to be released to drop by their own weight into proper brakingpositions upon the rails and in advance of the adjacent wheels.

While the objects herein set forth are the most important, it willnevertheless be understood that further objects will appear and that theinvention consists in the arrangement of parts hereinafter fullydescribed, illustrated in the accompanying drawings, and pointed out inthe appended claims.

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views: Figure 1 is a side elevation of the end portion of a carprovided with the present invention and positioned in its elevatedinoperative manner. Fig. 2 is a similar view with the device lowered inits operative position. Fig. 3 is a perspective view of the devicedetached and in its lowered operative position, with the rails shown indotted lines and the operating lever broken away, and Fig. 4 is aperspective view of a corner portion of the car body showing the brakelever and keeper mounted thereon, the lever being broken away.

Referring more in detail to the drawings, the car is illustrated asprovided with a Specification of Letters Patent.

truck 11 under its end portion and having the outer or end pair ofwheels 12, the car being positioned for traveling upon the track rails13.

' It will be understood that each end of the car is of identicalformation and that the present device is preferably provided at each endthereof so as to provide brake shoes for the forward wheels of the carin which ever direction the car may be traveling.

The car frame 1a is provided with opposite brackets 15 upon its underside within which brackets a rod 16 is journaled transversely beneaththe car. An arm 17 is rigidly secured at its upper end to said rod andextends downwardly therefrom. A brake operating lever 18 is pivoted tothe clip 19 carried by the car frame and the free end 20 of said leveris adapted to be grasped by the brakeman upon the car, while a keeper orhook 21 pivoted to the car is adapted to engage over the lever 18 for retaining the brake inoperative. A link 21 connects the lower end 22 ofthe lever 18 and the arm 17 and as will be evident, a movement of thelever results in a partial rotation of the rod 16.

Spaced apart curved forwardly projecting supports or bars 23 are rigidlysecured to the rod 16 and extend within the cut away portion 2 1 of anarch-shaped brake frame 25. The opposite lower ends of the frame 25 areprovided with fiat shoe plates 26 positioned perpendicularly to theframe 25 and adapted to flatly rest upon the rails 13 as best seen inFig. 3. Angular downwardly extending flanges 27 are carried by theplates 26 at their inner edges, which flanges are adapted to engage theinner faces of the rails. Opposite U-shaped brackets 28 depend below theopposite outer edges of the car frame 14, each being adapted to re ceivea rearwardly projecting arm 29 of the frame for guiding the frame in itsmovements. Chains 30 are secured to the frame 14 and are connected tothe upper edge of the brake frame 25 by having their lower endspositioned in the top perforations 31 of said brake frame.

With the mechanism positioned as illustrated in Fig. 1, the brake shoes26 are elevated above the track by reason of the suspension of the brakeframe 25 upon the arms 23, which arms are maintained elevated by theengagement of the hook 21 with the brake lever 18. Upon releasing thehook rails 13 in advance of the wheels 12.

21' from said brake lever, the frame 25 turns the rod 16 a partialrotation by reason of the weight of said frame, which latter descends toits operative position upon ltlie ie wheels 12 then travel upon the shoeplates 26 and engage the frame 25, and in this position the flanges 27are positioned inwardly of the rails. It will thus be seen by merelyreleasing the hook 21 that the brake shoes are instantly positioned foruse. hen desired to elevate the brake shoes, the forward Wheels arebacked off of the plates 26 and a rearward movement imparted to thelever 18 which turns the rod 16 and raises the supports 23 together withthe frame 25 and the hook 21 then being positioned to engage the lever18, the brake mechanism is retained inoperative.

While the forms of the invention herein shown and described are what arebelieved to be preferable embodiments thereof, it is nevertheless to beunderstood that minor changes may be made in the form, proportion anddetails of construction without departing from the spirit and scope ofthe in vention as set forth in the appended claims.

What I claim is 1. A device of the class described comprising incombination with a car, forwardly projecting curved support bars mountedtherebeneath, means for elevating and lowerlng said bars, an arch-shapedbrake frame freely mounted upon said bars and adapted for slidingmovement thereon during an actuation of said bars, and shoe platessecured perpendicularly upon the lower ends of said frame.

2. A brake mechanism comprising in combination with a car frame mountedupon traction Wheels, oppositely positioned brackets, a transverselypositioned rod jourshaped brackets depending from the outer edges of thecar frame, rearwardly projecting arms upon said brake frame guidinglypositioned within said U-shaped brackets, shoe plates having innerdepending flanges carried by the lower ends of said brake frame andadapted for seating upon the rails of a track when the forward carwheels are positioned upon said plates with the device in its operativeposition.

In testimony whereof I aflix my signature in presence of two witnesses.
